Durability of component vs Durability of system

[karsguy]

Hello all,
What is the difference between the component durability and system durability in the context of automotive systems like transmission, suspension etc? What methods are used for validation in virtual testing and physical testing in both cases?
Thank you

Durability for both frequently is done with test equipment like dynamometers and using multiple samples with Weibull statistics. Reliability and confidence are descriptive terms you can use to search for more information.
